Chinese Paper Standard Size Query

Tool Introduction

This tool provides a comparison table for China's standard D-series paper sizes. The D-series is a unique Chinese paper standard, widely used in books, magazines, office stationery, and other fields. With this online tool, you can quickly find the precise millimeter (width × height) dimensions for various paper specifications from D0 (Full Sheet) to D6 (Sixty-fourth Sheet), facilitating design, printing, typesetting, and other tasks, ensuring compliance with Chinese National Standard GB/T 19999-2003.

How to Use

1. Visit this online tool page.
2. In the “Chinese Standard Paper Sizes Comparison Chart,” directly look up the millimeter (width × height) data corresponding to your desired paper size.
3. The table clearly displays the names of D0 to D6 series papers (e.g., D0 Full Sheet, D1 Half Sheet, etc.) and their millimeter dimensions, allowing you to quickly obtain the required information.

Usage Example

Suppose you need to query the size of “D4 (Sixteenth Sheet)” paper; you can follow these steps:

• Operation Demonstration:

  In the comparison table of this tool, find “D4 (Sixteenth Sheet)” in the “Paper Size” column.

• Expected Output:

  In the “Millimeters (Width × Height)” column, you will see the corresponding size: 188×260.

  This means that D4 (Sixteenth Sheet) paper has a width of 188 mm and a height of 260 mm.

• More Examples:
  • If querying D0 (Full Sheet) paper size, the result is: 764×1064 mm.
  • If querying D2 (Quarter Sheet) paper size, the result is: 380×528 mm.

Frequently Asked Questions

• Q: What are China's D-series paper sizes? A: The D-series is a unique Chinese paper size standard, different from the internationally used ISO 216 (such as A-series, B-series). It is primarily based on a fixed full sheet size (D0), and then D1, D2, D3, and other series papers are obtained by successively folding it in half.
• Q: What is the difference between D-series paper and international A-series? A: The D-series is specified in China's National Standard GB/T 19999-2003 “Book and Periodical Formats and Their Dimensions,” mainly used for books, magazines, and office paper within China. The international A-series (e.g., A4) is based on the ISO 216 standard, with an aspect ratio of 1:√2 and an A0 area of 1 square meter, primarily used for international general office and printing. Their starting sizes and derivation methods are different, so the dimension values also differ.
• Q: Are the sizes in the table the finished sizes after cutting? A: The sizes provided in this comparison table usually refer to the finished size (net size) of the paper, which is the final size that can be directly used after cutting, folding, binding, and other processes. In actual printing and production, bleed (trimming allowance) dimensions may need to be reserved.

Origin and Characteristics of D-series Paper

China's D-series paper size standard originates from National Standard GB/T 19999-2003 “Book and Periodical Formats and Their Dimensions.” This standard was formulated to adapt to the historical customs and practical needs of China's publishing and printing industry. The characteristic of D-series paper lies in its format: D0 is a full sheet, and then D1 (Half Sheet), D2 (Quarter Sheet), D3 (Eighth Sheet), etc., are obtained by successively folding it in half. Its dimensions do not strictly follow a 1:√2 aspect ratio but are determined based on specific printing and binding modules to achieve the most economical and reasonable paper utilization. The D-series is widely used in textbooks, periodicals, newspapers, and some office papers in China.

Notes

• This tool provides D-series paper sizes as specified in China's National Standard GB/T 19999-2003, which differs from international ISO standards (such as the A-series). Please note the distinction.
• The dimensions in the table are all in millimeters (mm), in the format of “width × height.”
• When designing and printing, please be sure to reserve sufficient bleed (printing margin) according to actual needs and printer requirements, to avoid content being cut off during trimming.
• For professional printing and publishing, it is recommended to re-verify the latest industry standards or confirm specific size requirements with your printing service provider.
